Error Log - Safe to Save and Close?

Hello all.

Just working on my latest track and decided to export. Set it off and walked away. Came back to find the log open with some AudioSource errors in it. I hit play to see if the session was still alive and it plays, but AudioSource errors kept on comming up. I then tried to save again and got the final error -

[ERROR]: AudioSource: cannot open peakpath (b) “/media/Studio/Ardour/Amputation/peaks/Vox 2-2%A.peak” (Too many open files)

[ERROR]: Unable to Copy file /media/Studio/Ardour/Amputation/Amputation.ardour to /media/Studio/Ardour/Amputation/Amputation.ardour.bak (Too many open files)

I dont want to lose data so I’m wondering if anyone knows whether these are benign or not.

Using Ardour 3.5.403 on a Tango Studio set up.

Cheers

Update:

The error log keeps growing even when not playing:

Please stop using 3.5.403 and upgrade to 4.x. These issues are fixed.
